Question

If m∠7 = 105, what is the measure of ∠10?

A. 15°
B. 105°
C. 75°
D. 95

Answer 1

∠7 = ∠15
∠10 = 180 - ∠15
∠10 = 180 - ∠7
∠10 = 180 - 105
∠10 = 75

Answer 2

If m∠4 = 65, what is the measure of ∠1?

A. 25°
B. 65°
C. 115°
D. 135°
can you help w. this one too please?

Answer 3

Same thing, different angles
∠4 = ∠2
∠1 = 180 - ∠2
∠1 = 180 - ∠4
∠1 = 180 - 65
∠1 = 115

Answer 4

oh okaay so is that how you set it up always??
